Latest Vesicle Stories
A team of researchers has managed to obtain 3D images of the vesicles and filaments involved in communication between neurons.
Although they are present almost everywhere, on land and sea, a group of related bacteria in the superphylum Planctomycetes-Verrucomicrobia-Chlamydiae, or PVC, have remained in relative obscurity ever since they were first described about a decade ago.
Communication between nerve cells is vital for our bodies to function.
The transmission of information from one neuron to the next is an unseen intricate ballet.
Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.
A research team at the University of California, San Diego School of Medicine has provided a surprisingly simple explanation for the mechanism and features of the "Golgi apparatus" â€“ a structure that has baffled generations of scientists.
New data on signaling proteins, called G proteins, may prove important in fighting diseases such as cardiovascular, neurodegenerative disorders, and cancer.
As part of the intricate ballet of synaptic transmission from one neuron to the next, tiny vesicles â€“ bubbles containing the chemical neurotransmitters that make information exchange possibleâ€”travel to the tip of neurons (synapses), where they fuse with the cell's membrane (a process called exocytosis).
Success in soccer sometimes comes with "bending it like Beckham." Success in cellular fusion â€” as occurs at the moment of conception and when nerve cells exchange neurotransmitters â€” requires that a membrane be bent before the merging process can begin, University of Wisconsin-Madison researchers have shown.
A new advanced method for nano-scale imaging of vesicle-fusion â€“ vesicles are biological nano-sized containers - could add to our understanding of diseases of the nervous system and viral infections.
Phallusia nigra is a species of sea squirt (tunicate) found in tropical seas around the world. It is usually found in shallow waters attached to any hard substrate. It is a solitary animal rather than living in colonies. Although the native range of this animal is unknown, the tropical western Atlantic Ocean, the Red Sea and the Indian Ocean are possibilities. Like all ascidians, this species has a thick leathery envelope (tunic) containing cellulosic material. The tunic encloses a...
